EVERYTHING YOU NEED TO KNOW ABOUT CALCIUM & 15 NON-DAIRY FOODS PACKED WITH CALCIUM

When you think of calcium, usually teeth and bones are most often associated. But according to The Vegan Society, an organization founded in 1944 that is dedicated to providing information on the benefits of a vegan diet, calcium is also involved in your nervous system, blood clotting and controlling your muscles.

Calcium is the most abundant mineral in the body, making up one to two percent of a healthy adult’s body weight. 99 percent of the calcium in our body is stored in teeth and bones, and the body maintains a consistent concentration of calcium. However, if you are not consuming sufficient calcium through diet, your body will extract the calcium it needs from bone tissue, thereby accelerating bone loss.

Calcium requirements are dependent upon age. The recommended daily allowance (RDA) for adults age 19-50 is 1000 mg. That number increases to 1200 mg for women beginning at age 51 and for men beginning at age 71.

Contrary to popular belief, you do not need dairy milk to obtain calcium. When in actuality, people who consume dairy products retain less calcium than those who get their calcium from veggies. A Harvard Nurses’ Health Study found that consuming two or more glasses of milk a day put people at a higher risk for broken hips and arms than those who drank one or fewer glasses of milk a day. 

Many decide to opt out of cow’s milk and other dairy products because of the immense cruelty involved in the dairy industry, as well as the environmental impact. Cow’s milk is for well, baby cows. Calves are stolen from their serially pregnant mothers, all for humans to drink their milk. 

 But simply put, there is no need for humans to consume cow’s milk or any other dairy product, despite what The National Osteoporosis Society may tell you. Calcium recently made the news when a National Osteoporosis Society’s survey that showed a fifth of young people are avoiding or cutting out dairy has been misrepresented in the media. Many of the articles alleged that cow’s milk is the only source of calcium, but The Vegan Society was quick to point out that there are many easily available vegan alternatives.

“Some media reports exaggerate the findings, making it sound like dairy is the only source of calcium and failing to note the alternative sources that can be easily obtained on a vegan diet,” noted Heather Russell, a Dietitian at The Vegan Society.

Updating this article 12/18 with some great facts and studies from Dr. Michelle McMacken, Board-Certified Internal Medicine Physician and known as the veg_md.

“1- Do ensure your getting enough CALCIUM. The RDA for adults is 1000 mg/day for women,, 50 yrs and men 70 yrs. Low oxalate greens are an outstanding source, so make it a daily habit to eat broccoli, bok choy, kale, napa cabbage, mustard or turnip greens. We absorb 40-60% of the calcium in these greens, vs about 30% from cow milk. Fortified nondairy milks and calcium set tofu are other good sources, with absorption equivalent to that from cow milk. Also enjoy collard greens, sesame tahini, beans almonds and almond butters! (Note: Swiss chard and spinach have calcium but it’s bound to oxalate and thus not well absorbed.)

2- MAXIMIZE your FRUITS, VEGGIES & BEANS. You’ll get plenty of folate, Vitamin C, K and plant protein ,all conducive to healthy bones.

3- Pay attention to VITAMIN D, as it’s essential to calcium absorption. Most people need a Vitamin D supplement, especially those living in cooler climates or adequate exposure to sunlight.

4- Avoid excessive, SALT, ALCOHOL & CAFFEINE. They increase calcium losses or impair absorption.

5. Get regular EXERCISE – weight bearing and strength training.

Why avoid dairy in the first place, from the nutrition perspective? Well, dairy fat is a major contributor to heart disease, and stroke risk. All dairy, including low fat, increases IGF-1 9 (a hormone tied to cancer risk) and naturally contains estrogen and bloating in the up to 70% of people worldwide who lose the ability to digest lactose, causing gas and bloating in the up to 70% of people worldwide who lose the ability to digest lactose after childhood. And it’s linked to a higher risk of prostate cancer, type 1 diabetes, colitis and acne – not to mention colic, constipation, and iron deficiency in children. More info at VeganHealth.org”
